LUBRIcnTING .nnvrcnj Specification of Letters Patent. P te t June 0, 1 1;

Application filed January 15, 1915. Serial No. 2,327. i

To all whom it may concern:

Be it known that we, SIMON BRUGELA'RIE and ALFRED Fnisz'r, citizens of the United States, residing at West Hoboken, inthe county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Lubricating, Devices, of which the following is aspecification.

This invention relates to lubricating devices, and has for its object to provide a lubricating attachment for the ordinary die stock, without necessitating any material changes inthe construction of the latter.

Another object of the invention is to utilize, for the lubrication of dies, the operating lever.

Other objects and aims of the invention, more or less broad than those stated above, together with the advantages inherent, will be in part obvious and in part specifically referred to in the course of the following description of the elements, combinations, arrangements of parts, and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims.

In the accompanying drawings, which are to be taken as part of this specification, and in which we have shown a merely preferred form of embodiment of the invention, Figure 1 is a top plan view illustrating a die stock provided with our invention, parts being broken away; Fig. 2 is a detail sectional view illustrating the valve that controls the flow of lubricant, and its relation to the end of the hollow operating lever, and Fig. 3 is a similar view illustrating the means for controlling the said valve.

Referring to the numerals on the drawings, there IS shown at 4 a die stock, which is provided with the usual jaws 5 for holding the cutting dies 6. For the operation of these die stocks it is the practically universal custom to employ a hollow lever 7, which is screw-threaded at one end as indicated at 8 and detachably secured in the correspondingly interiorly threaded socket 9, which latter is carried by the die stock. It is also the ordinary practice to provide the die stock with two of such socket members, arranged diametrically opposite to each other, and with very heavy work a hollow handle 7 is inserted in each one of the sockets 9.

It is the characteristicof our invention that we utilize the interior of the hollow handle as an oil reservoir, providing a dischargev outlet adjacent the 7 cutting dies, and controlling the discharge from the outer end of the hollow lever. Accord: ingly, there is .adischarge conduit 10, which. is. tapped into the wall of the socket me'mber 9, as indicated at 11, and the piper? is provided near one end with a valve seat 12. Cooperating with this valve seat is a; reciprocating .valve 14 carried at one endof a rod 15, this rod 15 extending through the pipe 7 and carrying on its outer end a cross piece 16 secured as by means of a screw '17. Y Thiscross piece 16' is keyed-"into or may be integral with an interiorly threaded thimble 18, which engages a correspondingly threaded tubular piece 19. This tube 19 is threaded into a collar 20 and secured thereto by means of a screw 21, and a washer 22 abuts against the end of the tube 19.

Adjacent the washer 22 we provide suitable packing 24, which is compressed be tween the washer 22 and an interiorly threaded thimble 25, which is held between the end of the hollow handle 7 and said packing. The pitch of the threaded con nections between the rod 15, the threaded thimble 25 and the threaded thimble 18 and the tubular piece 19 is of diilerent degree so that the movement of the thimble 25 may be relatively greater or less than that of the rod 15. In this manner the degree of compression of the packing may be varied to suit the various grades of oil that may be used instoeks of this character. It is obvious that upon turning the thimble 18, the rod 15 will be caused to move so as to control the valve seat 12, so that whenever it is desired to discharge oil from the inner end of the pipe 7, this may be readily accomplished. The means for controlling the valve is placed at the outer end of the pipe 7 so as to interfere as little as possible with the use of the lever as such, and the packing insures that there will be no leakage of oil from the outer end of the reservoir when the lever is in a down position.

Inasmuch as many changes could be made in the above construction, and many apparently widely difierent embodiments of our invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense. It is also to be 0, 155: this ,patent may he obtained for understood that the language used" in following claims is intended to cover all the lever opening into the socket said'operatinglever constitutin an oil reservoir and bein V I b I I b provided with a valve seat ad acent its inner end, a reciprocating valve. cooperating with the valve seatand including a rod, said rod extending through the hollow lever, packing for said rod adjacent its outer end, and

operating means adapted to cause reciprocation of the rod, said last-named means in-- eluding agthimble connectedto the outer end of the rod and having screw-threaded. conlever.

nectiinjwith outer eiid of hollow 2. In a device oft'he kind described, a hollow handle, a valve seat therein, a reciprocating'rod located within the handle and having a valve at one end thereof and a threaded means at the opposite end for re 7 ciprocating s-aidrod, a packing adjacent one end of the rod, a thimble arranged to engage said packing and means associated with the rod and'thimble to place the packing under compression when the said-rod is moved in one direction.
